Abstract
The invention provides a compound fertilizer suitable for lettuce cultivation in low-fertility and medium-fertility districts. According to the invention, the maximum of the fertilizer efficiency of the compound fertilizer is achieved via an optimization for the component preparation of the compound fertilizer. The compound fertilizer is especially suitable for soils in south Anhui mountainous areas, and high in application prospect.
Description
Technical field
The present invention relates to a kind of composite fertilizer, be specifically related to the composite fertilizer of low fertility area lettuce planting in a kind of being applicable to.
Background technology
The advantages such as that composite fertilizer has is low in the nutrient content, minor component is few and physical behavior is good, for balance fertilizing, low utilization rate of fertilizer in carrying promotes the middle low yield stable yields of crop that very important effect is arranged, and is the important substance basis of low crop yield in carrying.But it also has some shortcomings, and is always fixing such as its nutrients ratio, and different soils, required nutritive element kind, quantity and the ratio of Different Crop are various.Be directed to unique landforms and the soil characteristic of Wannan mountainous area, if only do not use Common compound fertilizer for edatope, then not only can affect the output of farm crop, also can affect the agricultural-food mouthfeel.
Summary of the invention
For above the deficiencies in the prior art, the invention provides the composite fertilizer of low fertility area lettuce planting in a kind of being applicable to.
The present invention is achieved by the following technical solutions:
The composite fertilizer of low fertility area lettuce planting in a kind of being applicable to, nitrogen, phosphorus, potassium mass content are 20-11-16 in the described composite fertilizer, and the mass content total amount of nitrogen, phosphorus, potassium is 47%;
Contain micro-Mn, Mo and Cu in the composite fertilizer, content is 0.7%;
Above-mentioned each component raw material is pulverized granulation behind the mixing, again drying, cooling, screening, the composite fertilizer of low fertility area lettuce planting in namely obtaining being applicable to.
Beneficial effect of the present invention is: by the optimization to composite fertilizer's component preparation, reach the maximization of composite fertilizer's fertilizer efficiency, be specially adapted to the soil of Wannan mountainous area, has larger application prospect, the output of low farm crop in not only can increasing, also can reach the purpose of low agricultural-food mouthfeel in putting forward, make agricultural-food more adapt to social demand, more meet people's needs.
Embodiment
The invention provides in a kind of being applicable to the composite fertilizer of low fertility area lettuce planting, wherein nitrogen, phosphorus, potassium mass content are 20-11-16, and the mass content total amount of nitrogen, phosphorus, potassium is 47%.Also contain micro-Mn, Mo and Cu in the composite fertilizer, content is 0.7%.
Above-mentioned each component raw material is pulverized granulation behind the mixing, again drying, cooling, screening, the composite fertilizer of low fertility area lettuce planting in namely obtaining being applicable to.
The present invention is by the optimization to composite fertilizer's component preparation, reach the maximization of composite fertilizer's fertilizer efficiency, be specially adapted to the soil of Wannan mountainous area, has larger application prospect, the output of low farm crop in not only can increasing, also can reach the purpose of low agricultural-food mouthfeel in putting forward, make agricultural-food more adapt to social demand, more meet people's needs.
